Substitute for Oil in Banana Bread
Best Substitutes
| Oil Substitute | Rating | Substitution Ratio for Banana Bread | Ideal For | Flavor | Adjustments |
|---|---|---|---|---|---|
| Melted butter (unsalted) | Best | 1:1 by volume (1 cup butter per 1 cup oil) | Classic, bakery‑style loaves with tender crumb | Buttery, slightly richer than oil | Optional: add 1–2 tbsp milk/yogurt per cup for extra moisture; don’t overmix |
| Sour cream (full‑fat) | Good | 1:1 by volume | Rich, dense‑moist “bakery” crumb | Subtle tang, creamy richness | If batter is thick, add 1–2 tbsp milk; check doneness toward center |
| Full‑fat Greek yogurt | Good | 1:1 by volume | Ultra‑moist, tender loaves with slight tang | Mild tang; clean dairy finish | If very thick, thin with 1–2 tbsp milk; bake 5–10 min longer |
| Unsweetened applesauce | Good | 1:1 by volume (or 3/4 cup applesauce + 2 tbsp milk) | Lower‑fat, very moist loaves | Light apple note; less rich | Reduce sugar by 2–3 tbsp per cup; extend bake 5–10 min; avoid overmixing |
| Extra mashed banana | Works | 1:1 by volume | Intense banana flavor, rustic texture | Very banana‑forward; less buttery | Reduce sugar by 2–4 tbsp; add 1/4 tsp extra baking soda per cup; bake longer |
| Smooth nut butter (peanut or almond) | Works | 3/4 cup per 1 cup oil, whisked with 1/4 cup milk | Hearty, protein‑boosted loaves | Nutty; noticeably changes flavor | Warm to loosen; do not overmix; may need 5–10 extra minutes bake time |
What Bakers Say
Real bakers share what worked for them when replacing oil in banana bread — from substitution ratios to texture fixes.
Read baker experiences
"When I swapped the oil in a boxed banana bread mix for butter, it turned out drier; oil keeps quick breads moister, so I was advised to stick with oil."
Reddit user (r/AskCulinary)•using a store‑bought banana bread mix"If you replace butter with oil, don’t go 1:1; butter is ~80% fat, so reduce the oil to about 80% of the butter amount. Also, changing pan types can throw off bake time and texture."
Reddit user (r/Baking)•troubleshooting an oily, dark banana bread"Replacing only half the oil with applesauce works well; I also bring the applesauce to room temp first for better texture."
Reddit user (r/ididnthaveeggs)•general quick breads including banana bread"For a fluffier crumb with oil, I whip eggs with sugar first and add the oil later; using about 80% oil for 100% butter and adding a little yogurt also helps."
Reddit user (r/AskBaking)•tips shared in a dense‑vs‑fluffy banana bread thread"Coconut oil works really well in banana bread; another commenter even preferred walnut oil over butter for flavor."

Choosing the Right Substitute
Oil in banana bread provides tenderness, moisture retention, and a soft crumb because pure fat inhibits gluten development and keeps the loaf from drying out. When choosing a substitute, balance fat content (for tenderness), water content (affects crumb and bake time), and flavor impact (butter adds richness; yogurt/sour cream add tang; fruit purees add sweetness and density). Banana bread is forgiving, but thicker, water‑heavy swaps often need a slightly longer bake and minor sugar or leavening tweaks.
Our Top Choice: Melted Butter
Melted unsalted butter replaces oil cleanly while adding classic buttery flavor and a tender crumb. Swap 1:1 by volume; for the same plush moisture as oil, stir in 1–2 tablespoons milk or yogurt per cup of butter and avoid overmixing.
Another Great Option: Full‑Fat Greek Yogurt
Greek yogurt creates an ultra‑moist, tender loaf with a subtle tang that complements banana. Use a 1:1 swap; if your yogurt is very thick, thin slightly with milk and expect a 5–10 minute longer bake to set the center.
For Lighter, Lower‑Fat Loaves: Unsweetened Applesauce
Applesauce provides moisture without added fat, producing a soft but slightly denser crumb. Replace oil 1:1 and reduce sugar a bit to balance sweetness; extend bake time and mix gently to avoid gumminess.
For Rich, Tangy Moisture: Sour Cream
Full‑fat sour cream yields a plush, bakery‑style crumb with gentle tang and great keeping quality. Swap 1:1; if the batter is very thick, add a splash of milk and bake until a tester comes out with a few moist crumbs.
In a Pinch: Extra Mashed Banana
Using more banana amplifies flavor and keeps the loaf moist but denser. Swap 1:1, reduce sugar slightly, and add a touch of extra baking soda to help lift the heavier batter.
When You're Out of Options: Smooth Nut Butter
Whisk nut butter with milk to mimic oil’s fluidity for a hearty, flavorful loaf. Use about 3/4 cup nut butter plus 1/4 cup milk per 1 cup oil; expect a pronounced nutty taste and a slightly longer bake.
